摘要： PROBLEM TO BE SOLVED: To provide a bearing damage diagnostic method and a damage diagnostic system capable of discriminating bearing damage classification simply and accurately.
SOLUTION: In this bearing damage diagnostic method for detecting a bearing damage based on an AE signal acquired by an AE sensor installed near the bearing, each discrimination processing is performed, which is different between an initial operation stage wherein the repeated number of times generated by bearing rotation is below a prescribed number and a long-term operation stage wherein the repeated number of times is over the prescribed number. Initial operation stage measurement (S2) has the first discrimination process (S3) for discriminating existence of a damage based on an output value of the AE signal, the second discrimination process (S4) for discriminating existence of a nonmetal foreign substance interminglement by comparing the output value with a threshold set beforehand, and the third discrimination process (S5) for discriminating between a pre-existing damage and a metal foreign substance interminglement based on an AE generation portion. On the other hand, the long-term operation stage has the fourth discrimination process (S7) for discriminating existence of a fatigue damage based on the number of events of the AE signal. Each process is performed successively until damage classification is specified.
